ROLLER SEAL-PRESS.

SPECIFICATION forming part of Letters Patent No. 431,763, dated July 8, 1890. Application filed January 26, 1886. Serial No. 189,825. (No model.)

To aZZ whom, it may concern:

Be it known that I, EDWARD J. BROOKS, a citizen of the United States, residing at East Orange, in the State of New Jersey, have invented a' new and useful Improvement in Roller Seal-Presses, of which the following is a specification.

This invention is additional to myimprovements in seal-presses set forth in Letters Patent No. 319,387, dated June 2, 1885, and No. 328,106, dated October 13, 1885, relating, in common therewith, to improved means for compressing the leaden disks of seals which are so fastened, and impressing them with distinguishing-marks by rolling, in contradistinction to stamping or rectilinear pressing.

The present invention consists in a novel combination of parts, whereby the bed-roller, which is carried forward by the seal-disk in the pressing operation, may be and is returned preparatory to the next pressing operation, without the aid of springs, whereby the press is rendered springless, as hereinafter set forth and claimed.

A sheet of drawings accompanies this specification as part thereof.

Figure 1 of the drawings is an end view of a roller seal-press illustrating this invention. Fig. 2 is a side elevation of the die portion of the same, partly in section. Fig. 3 represents a cross-section on the line 3 3, Fig. 2. Fig. 3 represents a section on the line 03 00, Fig. 3. Fig. 4 is another side elevation of the die portion, partly in section, illustrating the pressing operation. Fig. 5 is an elevation of a pressed seal. Fig. 6 is a top view, and Fig. 7 is a longitudinal section, of the die portion of the upper or working lever-handle; and Fig. 8 is a complete side view of the press on a smaller scale.

Likelettersofreferenceindicatecorresponding parts in the several figures.

This improved roller-press has, in common with those shown in the previous patents hereinbefore referred to, a pair of lever-handles A B; a pair of cheeks C C, integral with said lever-handle A; a segmental roller-die D,

operated by said lever-handle B, and preferably integral therewith, as set forth in said Patent No. 319,387 a lower roller-die or bedroller E, which coacts with said roller-die D and is moved by the interposed seal-disk in the pressing operations, as illustrated by Fig. l; mechanical means F, forautomatically returning said bed-roller to the position in which it is shown in said Fig. 4, preparatory to the pressing operations, and a gage-stop G, integral with said cheeks 0, connecting the latter between the lever-handles, for arresting the seal-disk of the seal S between the roller-dies in proper position preparatory to the pressing operation,as shown in said Fig. 4, said parts being united by a pair of pivotpins P Q, parallel with each other and with the end of the press, (seen in Fig. 1,) upon which said roller-die D and bed-rollerE freely oscillate, and which extend through both of said cheeks, and are secured in place by expanding their smaller ends, as shown in Fig. 3.

To provide for dating each seal, as represented by Fig. 5, at the pressing operations, said roller-die D is' constructed with a peripheral recess 1" in that portion of it which is its upper or outer portion when the press is closed, and viewed as in Fig. 2 or in Fig.

8. Two series of interchangeable dating-dies d m are fitted to said recess. Both datingdies are held in place by a sliding keeperspring 70, which works in a dovetailed way on the back of the roller-die, and is held in effective position, with one end overlying said dating-dies, by a spring-detent s, Fig. 7. Its retraction (represented by dotted lines in Fig. 7) is limited by a stud-pin 1o, working'in a stop-groove in the back of the roller-die. A seal S being in position within the press, as shown in Fig. 4, the lever-handle B is moved toward the lever-handle A. The seal is bit and compressed against the bed-roller E by the outer corner of the dating-die d, and the corresponding portion of the peripheral face of the roller-die D, which is indented to roughen it, and during the continuance of said movement of said lever-handle B the operation of compressing the seal-disk upon the shackle-wire of the seal and providing it withimpressions of the dating-characters and other marks of said roller-die and bed-roller is completed, the seal-disk and bed-roller moving forward in unison with the rollerdie, as represented by the arrows thereon in BROOKS, or EAST oRANcE, NEw JERSEY, ASSIGNOR TO THE 8 J. BROOKS & COMPANY, OF NEw YORK, N. Y.

said Fig. 4 and finally the pressed seal S is ejected in the finished condition represented by Fig. 5, leaving the parts in the positions represented in Fig. 2. Said means F of this improved press for automatically returning said bed-roller to the position in which it is represented in Fig. 4 is a sliding link, working in a groove 0, Figs. 3 3 in the inner side of one of said cheeks G, and coacting with cam-recesses b a in the contiguous ends of said roller-die D and bed-roller E, respectively, as clearly shown in Figs. 2, 3, and 4. Lugs at the respective ends of the link F project into the respective cam-recesses, as seen in Fig. 3. The inner or hub surfaces within the respective cam-recesses are their effective surfaces. When the lever-handle B is lifted relatively to thelever-handle A from its po sition represented in Fig. 2, said roller-die D turns therewith, and said effective surface within said cam-recess 1) acts on the upper lug of said link F, causing the link to slide and its lower lug to act on said effective surface within said cam-recess a, so as to turn said bed-roller E, as represented by the arrows on the respective parts in said Fig. 2. Consequently at the end of said operation of said lever-handle B, which is the ordinary press-opening operation, the bed-roller is in its position represented in Fig. 4 and ready for the succeeding pressing operation. It will be obvious that the dating-dies and their appurtenances may be omitted, and that known equivalent linkqnotion devices may be substituted for said link F and its appurtenances; or the latter may be duplicated at the respective ends of the roller-dies without materially departing from this feature of the press.

Having thus described my said improvement in roller seal-presses, I claim as my invention and desire to patent under this specification The combination, in a roller seal-press, of a pair of lever-handles, a roller-die carried by the pivot end of one of said lever-handles and constructed with a cam-recess in one or each end, a bed-roller moved in one direction by the seal at the pressing operation and constructed with a corresponding cam-recess in one or each end, and a link or links coacting with said cam-recesses to return said bedroller preparatory to each pressing operation, substantially as herein specified.

EDWARD J. BROOKS.
